Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and unnecessary details and functions for the present invention will be omitted during the description to avoid confusing the understanding of the present invention.

[0020] figure 1 A network structure diagram of a communication system according to an embodiment of the invention is shown. Such as figure 2 As shown, for ease of illustration, only one evolved broadcast / multicast service center (eBM-SC), one MBMS gateway MBMS GW, and two base stations eNB1 and eNB2 in the same single frequency network (SFN) area are shown , and UE1, UE2, and UE3, and some other devices, such as routers, are omitted.

[0021] In the case of LTE, the user plane interface between the MBMS gateway MBMS GW and the base station eNB is called the M1 interface, and the interface between the base station eNB1 and the base station eNB2 is called the X2 interface.

Abstract

The invention discloses a multimedia service data sending and receiving method, base station equipment and user equipment. The method includes following steps, receiving the information of sending sequences which show a plurality of multimedia service, generating starting index of each multimedia service and scheduling information in the corresponding number of the index; sending the data of each multimedia service based on the sending sequence information and scheduling information. The method and equipment of the invention can realize the dynamic scheduling of MBMS in a monochromatic network so as to save power of user facilities in the condition of discontinuous transmission and make statistic multiplexing processing easy.

Description

technical field [0001] The invention relates to a multimedia data sending and receiving technology, in particular to a multimedia service data sending and receiving method, base station equipment and user equipment, capable of realizing dynamic scheduling of MBMS services in single frequency network transmission. Background technique [0002] 3GPP (Third Generation Partnership Project) launched the long-term evolution research project (LTE: Long Term Evolution) in 2005, hoping to meet the growing needs of operators and users with higher data throughput and better network performance provide support. [0003] Multimedia Broadcast / Multicast Service (MBMS: Multimedia Broadcast / Multicast Service) is a service introduced by 3GPP Re1.6, which refers to a point-to-multipoint service in which a data source sends data to multiple users, so as to realize the and access network) resource sharing, with as few resources as possible to achieve services for as many multimedia users with t...
